Which point is plotted on the graph? More than 1 choice

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
